Running SNMP on windows

2012-10-29 Thread Gaelle Nsengiyumva
Hi,
I am learning how to use SNMP and i found the tutorials/source code (
http://net-snmp.sourceforge.net/tutorial/tutorial-5/toolkit/demoapp/index.html)
on your website.
Am using windows 7, but I can also use a QNX server to run the program. Any
directions on how to do this?
Is there a particular environment I should run it in?

Thanks,

 From the master branch. I've just backported that feature to the 5.7 
branch.

I must be missing something; I can't find that in net-snmp-5.7.2.tar.gz
Where did your README.win32 come from?

& README.win32 could use an update:
  "...  The dependency on the
   Cygwin dlls can be eliminated with the --mno-cygwin compiler flag,"

--mno-cygwin was dropped in version 1.7 of cygwin

No.

The first case is an array,
so sizeof(scalar_oid) gives 36 (assuming a 32-bit system),
and hence  OID_LENGTH gives 9
(sizeof(scalar_oid)/sizeof(oid))

The second case is a pointer,
so sizeof(scalar_oid) gives 4 (again, assuming a 32-bit system)
and hence  OID_LENGTH gives 1
(sizeof(scalar_oid)/sizeof(oid))

Glad you got things sorted.

Re: Debugging SNMP

2012-10-29 Thread Sverre Moe

I'm not sure if I found a solution to my problem, but anyway 
netsnmp_handler_registration *handler_reg = 
netsnmp_create_handler_registration(buffy, 
handle_snmp, 
scalar_oid, 
OID_LENGTH(scalar_oid), 
HANDLER_CAN_RONLY); 



I tried to output each handler, and rootoid_len that comes from 
OID_LENGTH(scalar_oid) was 1 for all scalars. I reckon this value should be the 
length of the OID (1.3.6.1.4.1.40463.2.1 = 9). 


I have my own wrapper class around an OID with the length, when I used this 
length instead of OID_LENGTH(scalar_oid), it registered all my scalars with no 
duplicates. 


Why does this work for my 3 hard coded scalars, but not my list of scalars? 
const oid scalar_oid[] = { 1,3,6,1,4,1,45678,1,1 }; 
OID_LENGTH(scalar_oid) gives value 9. 
const oid *scalar_oid = wrapper.getOid(); //Has same oid within. Returns a 
pointer to an oid. 
OID_LENGTH(scalar_oid) gives value 1. 


Both of these is just a pointer right? So why does OID_LENGTH work one the 
first, but not the second? 





My immediate problem is solved. Thanks for all assistance.

Hmmm as far as I can tell, this structure should be unique, 
but this duplication could well be a symptom of the problem, 
rather than the underlying cause.

This is the section that specifies the OID being registered. 
Personally, I've always tended to use the raw packet dump 
rather than this formatted version - but as far as I can tell, 
this is trying to register either .1 (or possibly .1.12, 
though I can't immediately see where the 12 comes from!) 

What is the OID that this is intended to register? 
What do the other packet dumps look like? 
If they are all trying to register the OID .1, then this would 
explain where the duplicate registration failures are coming from! 


Have you managed to put together a dummy version of this 
module that we can use to try and reproduce the problem?

Re: Debugging SNMP

2012-10-29 Thread Sverre Moe

Thats correct, its the netsnmp_register_scalar which returns -1. Function 
netsnmp_create_handler_registration returns a pointer to an 
netsnmp_handler_registration. I have also tried to output the handler memory 
address, and its not always unique. Don't know if it has anything to do with 
the problem. My hypothesis is that perhaps it doesn't create an unique handler 
for each scalar. 


Could I create an netsnmp_handler_registration without the helper-function 
netsnmp_create_handler_registration? Perhaps that would solve the problem.

So the 'netsnmp_create_handler_registration' call succeeds

Either

NETSNMP_DS_LIB_DUMP_PACKET, 
++snmp_dump_packet); 
or 
debug_register_tokens("dump");

Put one or other of these statements into the main block of your 
subagent code - before the 'init_snmp' and similar setup. 
The first will turn on raw packet dumps (which are more compact, 
but less immediately meaningful). The second enables "parsed 
dumps" which are probably easier to follow, if a little verbose. 

If you're not sure what you are seeing, post the text of these dumps, 
together with what you think the OIDs being registered should be.

I have tried to seperate the registration call into two separate statements, 
same result. None of these are actually failing. When I call 
netsnmp_register_scalar(handler), it returns -1 which is 
MIB_DUPLICATE_REGISTRATION. 


How do I " Turn on packet dumps in the AgentX subagent" ?

Hmm that sounds suspiciously as if the OID that's getting passed 
to the registration code isn't the same OID that you're expecting.. 
Unfortunately, there doesn't seem to be any debug code within the 
registration processing, that can be used to check this. 
(but see below) 

Things that are perhaps worth trying: 

* Separate out this call: 
> int returnValue = netsnmp_register_read_only_scalar( 
> netsnmp_create_handler_registration(buffy, )); 

into two separate statements: 
netsnmp_handler_registration *r = 
netsnmp_create_handler_registration(buffy, )); 
returnValue = netsnmp_register_read_only_scalar( r ); 

which will at least indicate which of the two calls is failing. 

* Craft a dummy version of this module that just registers 
the three scalars (using the same approach), but doesn't 
try to implement the actual handler. Then try compiling this 
into the main agent code, rather than as an AgentX subagent. 

This will indicate whether it's an AgentX-specific problem 
or more general. 

* Turn on packet dumps in the AgentX subagent, to show 
the exact registration requests that are being made. 

This will confirm whether the OIDs being registered are 
indeed what you expect. 


That third is probably the easiest to start with. 
If you try the second, and still get nowhere, then please 
post the complete code of that dummy module, so we 
can try to reproduce the problem.

test1_oid,
OID_LENGTH(test1_oid),
HANDLER_CAN_RONLY
));



int returnValue2 = netsnmp_register_read_only_scalar(
netsnmp_create_handler_registration("test2",
handle_snmp,
test2_oid,
OID_LENGTH(test2_oid),
HANDLER_CAN_RONLY
));

etc...



This works fine and snmpget returns a value. However , if I put these 3 hard 
coded scalars OID in a list, iterate over that list and register them, I get a 
duplicate error.

for (oid_iterator) { //Overlook pseudocode here

const oid *oid_value = (*oid_iterator);
const char *buffy = tmp_string.c_str();
int returnValue = netsnmp_register_read_only_scalar(
netsnmp_create_handler_registration(buffy,
handle_snmp,
oid_value,
OID_LENGTH(oid_value),
HANDLER_CAN_RONLY
));
}

I don’t know in your case, but one reason is because of execution of a subagent 
code multiple times. So when you run your subagent with “./XXX &” make sure 
that the previous execution has already been stopped. And if you have compiled 
the code with master agent, In that case you have to replace your “ 
libnetsnmpmibs.so.X... “ files... and then you have to execute it as subagent.

I have checked the contents of each elements inputted into
int returnValue = netsnmp_register_read_only_scalar(
netsnmp_create_handler_registration(buffy,
handle_snmp,
scalar_oid,
OID_LENGTH(scalar_oid),
HANDLER_CAN_RONLY
));

For each iteration of the loop the OID and scalar name is unique. So why does 
it returns MIB_DUPLICATE_REGISTRATION?

Try printing out the value of 'scalar_oid' (and 'scalar_length')
each time round the loop.
What is the registration call *actually* being invoked with?
(as opposed to what you think it _should_ be invoked with)

It isn't necessary anymore to modify the Net-SNMP source code in order
to switch from semicolon to colon as a separator character. All you
have to do is to set the ENV_SEPARATOR character before running
configure. A quote from README.win32:

ENV_SEPARATOR=":" \
./configure \
--with-mib-modules="host agentx disman/event-mib examples/example" \
--with-out-mib-modules=host/hr_network
